Relationship between kbps and kHz

Hello,

I am currently working on the Blu-ray to understand its advantages and disadvantages. However, I am facing a small problem. I am studying the audio of the Blu-ray right now, but I don't understand the meaning of x'Kbps/y'Khz. It would be very helpful for me to have this information, so if you could help me understand, that would be really nice.

    It's relatively simple. The Khz is the frequency of your music/sound. In basic CD format, it is at 44.1 Hz (44100 Hz), but you can find things at 48000, 192000... The higher the frequency, the more you can hear the harmonics of sounds (within the limits of your eardrums, which generally hear from about 3000 to around 20000 Hz).

    Kbps is the audio encoding; or bitrate (kilobytes per second, I believe).
    You've probably heard of different audio formats (mp3, m4a, wav, flac, wma....)
    Basically, each format has a different encoding. The higher the bitrate (and thus the kbps), the better the quality will be.
    So for mp3, you have 128, 192... up to 320 kbps. (below 128, it's honestly very bad, sounds saturate, frequencies crackle...)

    The best is wav, which is lossless. It is encoded at 1411 kbps and 44100 Hz; it is the CD quality. It will also take up a lot of space, about 10 MB per minute.

    There you go, I think I've covered everything quickly^^.
